Note 1: Thermal properties are specified with product mounted on PC board with one square-inch of copper area and still air.
Note 2: This device is constructed using a unique set of packaging techniques that impose a limit on the termal profile the device can be
exposed to during solder attach and rework. This limit permits only the use of the solder profiles recommended in the industry stan-
dard specification, IPC/JEDEC J-STD-020A, paragraph 7.6, Table 3 for the IR/VPR and Convention reflow. Pre-heating is required.
Hand or wave soldering is not allowed.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(VIN = 10V, VBATT = 4.2V for MAX1736EUT42 or 4.1V for MAX1736EUT41, TA = 0°C to +85°C. Typical values are at TA = +25°C,
unless otherwise noted.) (Note 3)
